Could you please give this commit a proper commit message, that describes what it does? Just referencing to an issue isn't very friendly wrt searching / scanning of the commit log, and makes the commit message useless if the issue list ever gets lost. If you want to refer to an issue, use the "Fixes #2969" syntax somewhere in the commit message body (i.e. not the first line), which will even cause github to autoclose the issue.

The new example code in the repo with address 8 looks ok, it might also be useful to update the actual web page here:
http://www.arduino.cc/en/Tutorial/MasterWriter
with a note indicating that i2c addresses 0-7 should be avoided as those are reserved.

Indeed @agdl . This is not the first time. Hopefully it's the last

[bperrybap]

Huh? I'm now totally lost.
Is the Tutorial web page going to be updated to include a text note about not using reserved addresses 0-7?
Fixed examples is great but I think users should also be warned about using the reserved addresses in the descriptive text.

@bperrybap the on-line page take the code from git so it is automatically updated when the PR is merged. For the descriptive part i added this statement here:
www.arduino.cc/en/Reference/Wire

"However the addresses from 0 to 7 are not used because are reserved so the first address that can be used is 8. "

[bperrybap]

Cool. Very nice. Thank You.

Why is this closed?

So @agdl can make another one, with a proper commit message, and a proper PR title and a proper PR description
